And we can illustrate the formation of a precipitate by a stoichiometrically balanced equation:

$AgNO_3(aq) + NaCl(aq) rarr AgCl(s)darr + NaNO_3(aq)$

And because the nitrate and sodium ions are along for the ride, we could write a net ionic equation:

$Ag^(+) + Cl^(-) rarr AgCl(s)darr$

Bonds are broken, and bonds are formed in a new substance, and thus chemical change has manifestly occurred.

How would you compare the formation of positive ions with the formation of negative ions in terms of energy changes?

Ionization energies, are associated with the LOSS of an electron, and the formation of a positive ion.....i.e. $M(g) + Delta rarr M^(+)(g)+e^(-)$ And these should be an inherently ENDOTHERMIC process,...

What is the formation reaction of aluminum chloride molecule and its enthalpy of formation?

You may also mean the liquid or the gas, but I assume you mean the solid. Thus, I assume you mean the process that produces $"AlCl"_3(s)$ from the elemental states...

What type of reaction leads to the formation of a precipitate?

Typically, we examine a solubility equilibrium, where concentrations of (metal) cation, and (non-metal) anion occur such that their product exceeds a given constant, i.e. $K_"sp"$. And we can take one...

Why does a precipitate form when silver nitrate solution is added to sodium chloride solution?

And for your scenario: $Ag^+ + Cl^(-) rarr AgCl(s)darr$ Silver chloride would precipitate as a curdy, white solid. Of course you would mix of silver nitrate and sodium chloride to...

Which of the following anions would precipitate the most in the reaction of sodium salts with magnesium chloride? What could be done to increase the solubility of the precipitate?

Likely, sulfate... but you would have to do the experiment yourself to verify this. ...And this reaction is given by... $"Na"_2"SO"_4(aq) + "MgCl"_2(aq) -> "NaCl"(aq) + "MgSO"_4(s)$ $s_(MgSO_4)...

Does a precipitate form when a solution of sodium acetate and a solution of ammonium sulfate are mixed together?

The idea here is that you're mixing two that contain soluble and you're interested in finding out if an insoluble ionic compound can be formed by the reaction. Sodium...

Why does the green precipitate obtained from an iron (II) salt slowly turn brown when in contact with air?

When iron (ll) is exposed to air, oxidation will occur and it will form iron (lll) salt which gives the brown colour. Oxidation refers to the loss of electrons,...

Imagine that the system is allowed to come to equilibrium. How would each of the following changes affect the equilibrium? Indicate whether the change would favor the formation of more products, more reactants, or would not lead to any change?

Here is my reasoning. Let's treat the heat as a product and rewrite the equation as $"Ca"("NO"_3)_2"(aq)" + "CO"_2"(g)" + "2NaOH(aq)" ⇌ "CaCO"_3"(s)" + "2NaNO"_3"(aq)" + "H"_2"O(l) + heat"$...

If $Na_2S$ is added to a solution containing $AgCl$, a black precipitate of $Ag_2S$ forms. Why does this happen using Le Chateliers's principle?

Silver chloride $"AgCl"$ is barely soluble in water. It's aqueous disassociation to its component ions would thus be a reversible process. $"AgCl" (s) rightleftharpoons "Ag"^(+)(aq) + "Cl"^(-) (aq) $ $K_(sp)...

Compund Y produced an orange precipitate when reacts with 2,4-DNP. Compound Y gives a pale yellow precipitate when reacts with I2/KOH. Compound Y does not react with AgNO3/NH3. what is compound Y?

Ketones and aldehydes react with $"2,4-DNP"$ to give brightly coloured phenylhydrazones. Aldehydes can be oxidized fairly easily by ammoniacal silver ion to give a carboxylic acid, and a silver mirror...
